Water is a colorless, odorless and odorless transparent liquid at normal temperature and pressure. The melting point is 0 °c, the boiling point is 100 °c, and the density is 0. 9982, the density of the vast majority of substances increases with the decrease of temperature, while the water in 3. There is a maximum value at 98 degrees C, the volume becomes larger and the density decreases when the water is frozen. Water is a kind of amphoteric material; Water can react with many active metals such as K, Ca, Mg, Fe and many other less active metals, and F2, Cl2 and many other non-metallic elements; water is also easy to react with oxides of alkali metals and some alkaline earth metals, and can also react with some non-metallic oxides; Water can undergo hydrolysis reaction with many salts; Water has strong hydration, when many substances are dissolved in water, their molecules or ions can combine with water to form hydrates. Water is an important catalyst. Without trace amounts of water, some common reactions can hardly be carried out.
This product is obtained by preparing water for injection according to the production process of injection.
This product is colorless clear liquid; Odorless.
take 100ml of this product, add 0.3ml of saturated potassium chloride solution, and measure it according to law (General rule 0631). The pH value should be 50~7.0.
take this product and separate it into three test tubes, 50ml for each tube. Add 5 drops of nitric acid and silver nitrate test solution 1 ml in the first tube and add 5ml of barium chloride test solution in the second tube, 2ml of ammonium oxalate solution was added to the third tube, and no turbidity was allowed.
take 25ml of this product, put it in 50ml plug measuring cylinder, add 25ml calcium hydroxide test solution, plug and shake, place it, and no turbidity will occur within 1 hour.
take 100ml of this product, add 10ml of dilute sulfuric acid, after boiling, add 0.02 ml of potassium permanganate titration solution (0.10 mol/L), then boil for 10 minutes, and the pink color should not disappear completely.
According to the method under water for injection inspection, should comply with the provisions.
should comply with the relevant provisions under the injection (General Principle 0102).
Toxicity: non-toxic. The highest tolerance of human body is 2700/m2 volume surface, excessive drinking water will lead to cramps, due to the osmotic effect will lead to electrolyte imbalance, thus causing headache, confusion, severe cases will cause Coma or even death.
